I agree that's it's good to know liberal policies are nationally popular, but it should be concerning that Trump came closer to winning in 2020 despite doing 7 points worse than Hillary Clinton. The EC-PV divide is prone to swinging wildly, and while that could mean it shrinks in 2024, it could grow to +7. In the Senate foir instance, NH-Sen 2016 was the tipping point and that ended up voting 10 points to the right of the collective Senate PV over the course of these past 3 cycles. The House seems to be a bit less of a problem going forwards though.
I do think it should be concerning for the GOP though because they're relying on a delicate path to 270 that involves large states like TX and FL which narrowly vote to the right of the nation, but that might not be the case in 10 years from now, and they really have very few states to turn to; MI/WI/PA by themselves aren't enough to make up, NV/NH/ME are all pretty small, and NM/IL/MN/DE will take a lot of work and reaching out to new voters they don't do well with.
Contrary to my expectations, EC/PV became more of a problem, but the House (holding by 5 seats with a PV margin that would have generated a Biden loss) and even Senate (Biden winning 25 states with <5% NPV lead) became less of a problem.
The big question mark here is Texas, which would flip the EC advantage and potentially give Dems a long House majority if it starts voting left of the nation, but it makes the Senate almost likely R in a close election.
